Prevalence of reproductive diseases and its associated risk factors in crossbred dairy cows

Abstract

Reproductive diseases of crossbred dairy cows significantly reduce productivity which is of great concern of dairy producers worldwide. The objectives of this study were to determine the prevalence of reproductive diseases and its associated risk factors in crossbred dairy cows in selected areas of Bangladesh. The study was conducted at eight villages of Ullapara Upazila under Sirajganj district. A total of 197 dairy farms having 488 breedable crossbred dairy cows (395 cows + 93 heifers) were randomly selected. A questionnaire as well as examination of cows was made to collect data on occurrence of reproductive diseases. The overall prevalence of reproductive diseases was 39.4%. Among the diseases, post calving anoestrus was 8.6%, delayed puberty was 6.8%, repeat breeding was 5.7%, retained placenta was 4.7%, metritis was 3.9%, dystocia was 3.3%, vaginal prolapse was 2.7%, abortion was 2.1% and uterine prolapse was 1.6%. The body condition score (BCS) of cows significantly (P<0.05) influenced the occurrence of reproductive disease. However, feeding practice, suckling, milk yield and parity did not influence significantly (P>0.05) the occurrence of reproductive diseases in crossbred dairy cows. In conclusion, further studies are needed with more number of cows to confirm the findings DOI: http://dx.doi.org/10.3329/ralf.v1i1.22357 Res. Agric., Livest. Fish.1(1): 71-79, Dec 2014

A cross sectional study on clinical trends of reproductive performances and reproductive disorders of dairy cows in Rajshahi district of Bangladesh

“…It is suggested that in order to combat the occurrence of reproductive disorders in cows crossbreeding program through artificial insemination (AI) should be done proper hygienic management. About 2.4% vaginal prolapse were observed which agrees with the findings of 2.2% and 2.7% reported by Sarder et al (2010) and Alam et al (2014), respectively. The prevalence of uterine prolapse was 1.4% in current study which is fairly agree with the findings of 1.3%, 1.4% and 1.6% obtained by Kader (2010), Sarder et al (2010) and Alam et al (2014).…”

“…About 2.4% vaginal prolapse were observed which agrees with the findings of 2.2% and 2.7% reported by Sarder et al (2010) and Alam et al (2014), respectively. The prevalence of uterine prolapse was 1.4% in current study which is fairly agree with the findings of 1.3%, 1.4% and 1.6% obtained by Kader (2010), Sarder et al (2010) and Alam et al (2014). The lower prevalence rate of vaginal and uterine prolapse may be attributed to the available of calcium supply with feed and less chance to occurred hypocalcaemia.…”

“…A 47.7% of dairy cows were having at least one of the reproductive problems observed by (Benti and Zewdie, 2014) in indigenous Borena breed cows in Borena zone in Southern Ethiopia. Contrasting to the resent finding, only 39.4% prevalence of reproductive diseases or disorders was reported in cross-bred dairy by (Alam et al, 2014) at Ullapara upazila under Sirajganj district. Haile et al (2014) recorded 43.07 % of cows were found to be affected either with one or more of reproductive problems.…”

“…In the present study about 11.4% cases found as repeat breeding cows, which agrees with the findings of 11%, 12.8%, and 13.08% reported by Shamsuddin et al (2007), Kader (2010) and Haile et al (2014), respectively. The occurrence of repeat breeding was higher than these values obtained by Gizaw et al (2007), Al Nahian (2011), Alam et al (2014), which were 8.91%, 6%, 5.7%, respectively and lower than 32.76%, 26.8%, and 15.9% reported by Khair et al (2013), Dinka (2013) and Esheti and Moges (2014), respectively. Mahmud et al (2014) investigated the prevalence and comparison of reproductive diseases and disorders of cows and reported repeat breeding syndrome 35.5% in BAU Vet.…”

Effect of mastitis on post-partum conception of cross bred dairy cows in Chittagong district of Bangladesh

“…There was a significant (P=0.01) variation observed in relation to the effect of mastitis on CI ( Table 4). The present study described the number of SPC was 4 which was comparatively higher in cows in which sub-clinical mastitis was converted to clinical, as described by Alam et al (2014).…”
